The cruise line said passengers affected by the illness had responded well to over-the-counter medication administered on board the ship.

The company said it enhanced cleaning on board the ship during the cruise to help prevent the spread of the illness.

After the ship docked, the company said it "conducted an extensive and thorough sanitizing on board the ship and within the cruise terminal, to help prevent any illness from affecting the next sailing."

Passengers who boarded The Majesty of the Seas Friday received a letter asking if they had experienced any gastrointestinal symptoms within the last three days. Those who felt uncomfortable were allowed to reschedule their trip, the cruise line said.
